FD Ladder Calculator: Split ₹5 Lakh Across 5 FDs, Explained

Priya, 34, has ₹5 lakh set aside that she does not need all at once. Her bank offers a decent five-year fixed deposit rate, but one question stops her: what if she needs ₹1 lakh in year two? Breaking a five-year FD early usually means a penalty and a lower rate. There is a middle path, and it needs no new product: split the money into a ladder.

FD laddering means splitting one lump sum into several fixed deposits maturing in different years — five ₹1 lakh FDs maturing in 1, 2, 3, 4 and 5 years. As each matures, spend it or reinvest it for five years. You trade a little simplicity for penalty-free access every year and protection against locking everything in at one rate.

Instead of putting ₹5 lakh into one five-year FD, you create five ₹1 lakh FDs with staggered maturities. The first matures after one year, the second after two, and so on. When a rung matures, you make a fresh choice: use the money, or roll it into a new five-year FD at whatever rate is available then. After five years of reinvesting, one FD matures every year.

Here is Priya's ladder using assumed illustrative rates, with annual compounding and figures before tax. These are not a bank's live offer for every tenure — check your bank's rate card before booking, because rates differ by tenure, amount and customer type.

Year 1: ₹1,00,000 at an assumed 6.25% becomes ₹1,06,250

Year 2: ₹1,00,000 at an assumed 6.40% becomes ₹1,13,210

Year 3: ₹1,00,000 at an assumed 6.50% becomes ₹1,20,795

Year 4: ₹1,00,000 at an assumed 6.50% becomes ₹1,28,647

Year 5: ₹1,00,000 at an assumed 6.45% becomes ₹1,36,687

Added together, the five maturities total ₹6,05,589 on ₹5,00,000 invested, or ₹1,05,589 in interest across the first cycle. The more useful number is the access it buys: by the end of year two, ₹2,19,460 has already matured penalty-free. Priya can handle an emergency from that, without touching the longer rungs.

For context, November 2026 round-ups put large banks' headline general-citizen FD rates at up to about 6.50% at HDFC Bank and 6.45% at SBI, with senior citizens up to about 7.05% to 7.10% on eligible tenures.

Laddering is risk management, not a return trick. Judge it on a stated framework, dated 4 November 2026, with these weights: penalty-free liquidity 40%, protection against rate moves 30%, deposit-insurance safety 20%, and simplicity 10%.

On liquidity and rate flexibility, the ladder wins clearly. On simplicity, a single FD wins — one booking, one maturity date, nothing to track. On total interest, a single ₹5 lakh FD held for the full five years at an assumed 6.45% would reach ₹6,83,437, or ₹1,83,437 in interest. That beats the ladder's first-cycle ₹6,05,589, but the comparison is not like-for-like: the ladder hands money back in years one to four, while the single FD pays nothing until year five.

At an assumed 5% annual inflation, that single FD's ₹6,83,437 is worth about ₹5,35,491 in today's money. FD interest may preserve capital in nominal terms while barely beating inflation after tax — another reason to treat the ladder as a liquidity plan, not a wealth-building engine.

Splitting ₹5 lakh into five FDs at the same bank does not multiply your deposit insurance. The Deposit Insurance and Credit Guarantee Corporation (DICGC) covers up to ₹5 lakh per depositor per bank, principal and interest combined, across all branches of that bank together. So if your total deposits plus interest at one bank exceed ₹5 lakh, the excess is not covered. The insurance benefit only appears when you split across banks: ₹15 lakh as ₹5 lakh each across three banks keeps each total within its own cover, while ₹15 lakh at one bank leaves ₹10 lakh outside it.

FD interest is taxed at your income-tax slab rate, not at a special FD rate. Banks deduct tax at source (TDS) at 10% with PAN once interest from that bank crosses ₹50,000 in a financial year for general citizens, and ₹1 lakh for senior citizens from FY 2025-26. TDS is not your final tax — it is adjusted when you file.

Breaking an FD early typically costs 0.5 to 1 percentage point off the applicable rate, and the bank may pay the rate for the period actually held. That is the cost a ladder avoids for a rung that has already matured, but it still applies if you break a longer rung early. Read the premature-withdrawal clause before you book, especially on special or tax-saver deposits, which have their own lock-ins.

Senior citizens generally earn an extra 0.50 percentage point on eligible deposits. On Priya's ladder maths, adding 0.50 points to every rung lifts the first-cycle total to about ₹6,14,538 — a useful illustration, not a promised rate.

1. Confirm how much you will not need for at least a year; keep nearer-term money out of FDs entirely.

2. Choose your rung size — equal rungs keep it simple; larger later rungs suit a known future expense.

3. Stagger maturities yearly, or quarterly if you want more frequent access.

4. Spread across banks if your total, including interest, crosses ₹5 lakh at any one bank.

5. Note every maturity date in one place, with a reinvest-or-spend decision for each.

6. On maturity, reinvest only after checking the current rate — never auto-renew blindly.

If you know you will need the full amount on one date, a single FD matched to that date is simpler. If rates are falling sharply and you will not need the money, locking the whole amount in now may beat a ladder. And if the money is your emergency fund for the next few months, do not put it in FDs at all — keep it instantly accessible.
